Try adding some snails or a cleanup crew. Also check your flow and alk!

Algae probs from low flow try adding a cleanup crew fish or snails

Scrape clean, do a water change after 10-20%. Keep the white spectrum low as possible with lighting while snails (turbo or astrea) do their work. Also, if not in use get a UV sterilizer for the water and make sure it flows below 300GPH so it can eliminate the cells. Hope it helps!

Like everyone else said, scrape the back wall water change. Get some turbos as much as they suck to deal with. They're going to knock over everything but they'll take care of that back glass

In my experience I haven’t always gotten the results I want from snails but recently I started to use a more fish heavy cleanup crew with mollies and lawnmower blennies on top of the snails and that has kept my tank almost completely clear of nuisance algae.
